are easily distinguished from tlie allied genera, ScijUa, Zupa, and 

 Aclieolus, by having the last or costal spine considerably longer than 

 the remaining eight spines of the antero-lateral margin." 



The recent species are tolerably numerous ; Neptiinus hastatus, 

 Linn., inhabits the Mediterranean, but for the most part these forms 

 occur within the tropics, as in the West Indies, the coasts of Brazil, 

 the Pacific, and the seas of India and Asia.
